Frequently Asked Questions

This is where you will find most answers. If there should still be any questions left, don’t hesitate to contact us.


Do we install in your city or town?

Although we are headquartered in the Texas Hill Country, we proudly install systems state-wide. For projects 75 miles or greater outside of Dripping Springs, our installations start at 5,000 gallons.

How do you calculate potential rainwater capture?

A good, basic rule of thumb for calculating your potential rainwater capture is as follows: Catchment area (sq. ft. of  roof) X rainfall (in.) X .62 conversion factor = Capture (gallons)

2400 SF x 32″ rain X .62 = 47,616 gallons of water collected annually

What kind of filtration is used for potable water systems?

For potable rainwater systems we use a sediment filter, followed by a carbon filter, and then a high flow UV light. This is all that is needed for rainwater, no other chemicals, salts or softeners required.

Does Harvest Rain use chlorine to disinfect the water?
No. Our systems do not require any chemical additives. Your water will instead be disinfected via a UV lamp.
If I do not maintain my system is there a chance I could get sick?

Yes, rainwater collection systems need consistent attention. Falling behind on general maintenance of filters, UV lights, gutters, leaf baskets, etc. can lead to contaminated water. We encourage a thorough review of your system at least every 3-6 months (depending on size of the system). Many people opt to replace their own filters, etc. but we also offer ongoing service maintenance agreements with our skilled service team.

How do I fill my tank once the rainwater system is installed?
The preferred method is rain! lf you can’t wait for rain, there are multiple bulk water distributors throughout Texas.
What kinds of pumps are used for rainwater harvesting?
Our preferred pump is a constant pressure submersible pump inside the tank. However, depending on the water system, tank style, water demand, house size and length of pipe runs, we may employ a different solution.
Can I use my own preferred gutter company?
Absolutely! However, it is critical that you instruct your gutter company to work with us on the design and implementation to ensure gutter grade, waterflow, downspout sizing, and downspout location among other things. Ideally, your gutter company and our crew will be on the job site at the same time.
What kinds of gutter screens are installed on Harvest Rain systems?
We strongly recommend leaf screens on all gutters, regardless of surrounding vegetation, a first flush tank and/or flush line, and a serviceable leaf screen basket on the underside of the tank lid.
What will the trenching look like after my rainwater system is complete?
There’s no way around it; trenching is disruptive to landscaping and grass. We will use commercially reasonable efforts to fill in trenches to grade and replace items moved, but we cannot make property look like it did before installation. Your land will be scarred but time will heal it.
How is a rainwater collection system paid for?
We require a 50% deposit to get your tank ordered and schedule you on our construction calendar. We collect the remaining 50% at the time of completion.
Does Harvest Rain offer financing?

No. At this time we do not offer our own in-house financing. We are happy to provide you with a list of rainwater-friendly lenders that we regularly work with.

Will Harvest Rain build a small weatherproof shed to house my filtration near the tank?
We prefer you, or a contractor of your choice, build these enclosures. Our experience shows that since this type of construction is not our specialty, our pricing is usually not competitive.
What is Harvest Rain’s warranty policy?
We offer a 1 year warranty on all workmanship; the pump, tank, UV light, and other items carry their own warranty which varies depending on the make/model. We cannot warranty against natural disasters.
What kind of warranty comes with the tanks Harvest Rain installs?
Most corrugated steel tanks come with a manufacturer’s warranty of 20 years; and most poly tanks come with a manufacturer’s warranty of 1 year or longer.
Can my HOA prevent a rainwater installation?

No, although an HOA can require certain design preferences as well as an approval process for a rainwater installation, Texas Property Section 202.007, states an HOA may not “unreasonably deny” a homeowner from installing rain barrels or a rainwater harvesting system.

Your HOA may even require rainwater systems in the case of impervious cover requirements.
